Abstract
A clamping unit () for machine tools () with a housing () connected in a rotationally fixed arrangement with a machine spindle, () and a screw drive () that interacts with a draw rod () such that rotational movements are converted into translational movements, the housing () being provided with an output element by which rotational movements are transmitted to an actuator (). The housing () has an input element in a rotating mounting, with the actuator () acting on the input element, and the input element () is in driving connection with a shaft () by means of intermediate elements (), whereby to direct rotational movements of the machine spindle () via the clamping unit (), and for adjustment movements of differently configured clamping devices, to be converted into axial adjustment movements and transmitted directly onto the draw rod (). No complicated electrical control devices and programs are required for adjusting and adapting a power chuck () linked to the draw rod () to different operating conditions.
